"We expect substantial same-store sales and profit growth in the second half given overall trends in sales and brand perceptions. Furthermore, the China Division remains on track to open at least 700 new restaurants this year, laying the groundwork for future growth," said Yum CEO Greg Creed in the release.

Analysts forecast China, a key segment for Yum, would be especially hard hit during the quarter following continued perception issues after a supplier scandal last year. Comparable sales in China were forecast to drop 8.4 percent, according to Consensus Metrix.

The restaurant company also reconfirmed its full-year 2015 EPS growth guidance of at least 10 percent.
